Our rail transit and bus experience includes light rail, commuter rail, heavy rail/subways, and city/regional bus systems. This experience includes primarily communications system planning, communications engineering, information systems/information technology services, and systems integration. We have worked on more than 20 transit systems and line extensions that have been built or are currently under construction.
We are a leader in implementing state of the art, open architecture, digital broadband data, audio and video communications systems. These systems utilize Gigabit Ethernet, Synchronous Optical Networks (SONET), Asynchronous Transfer Mode (ATM) switches, fiber optic and wireless communications backbones, Ethernet enabled station and remote devices, Ethernet access for serial data devices, user friendly man-machine interfaces, and ergonomically friendly control centers. Our broad range of transit system experience gives our firm the unique ability to understand the interfaces to all transit subsystems in the field, and as part of central control software and the man/machine interface. Our goal is to assist transit system operators in improving service to their customers by providing information to passengers and improving on time performance of transit systems.
Communications Based Train Control System - Las Vegas People Mover
Communications Based Train Control System Assessment. The Lamoreaux Group completed a technology assessment of the nearly completed communications based train control system (CBTC), including site survey, meetings with the contractor and subcontractors, and assessment report. The report focused on issues related to the CBTC system which were preventing reliable train to wayside communications. The system utilized 2.4 GHz frequency hopping spread spectrum wireless communications, as well as a 904 Mhz train tagging/beacon system. The report included an analysis of antenna placement, antenna selection, radio, amplifier and enclosure selections, as well as data communications between central control and wayside.

Newark Airport People Mover (Port Authority of New York and New Jersey)
Guideway Design and Construction. Magnetic Transit of America (MTA) proposed on a system to be installed at the Newark Airport, in Newark, New Jersey. LG was asked to develop guideway alignments to be used as part of the MTA proposal. LG developed a preliminary alignment to fit the existing stations, which had been constructed many years earlier in anticipation of installing a people mover at the Airport. Von Roll Transport Systems later won the contract to install the system. LG was then hired by Von Roll to assist in developing the final guideway alignment, and in preparing technical and procurement specifications and drawings for the guideway and power rail heating systems. LG proprietary software for Euler Spiral guideway alignments was used to develop the final alignment for the Newark System. LG also designed the maintenance and recovery vehicle and support equipment with 3D solids modeling. LG produced the following deliverables for Von Roll: Safety Plan, Security Plan, Failure Management and Winterization Plan.
Switching System Design. LG was called on to assist in reducing costs on the Swiss designed switching structures by preparing alternate switch conceptual designs.

Rio Casino People Mover (Las Vegas)
The Rio Hotel/Casino began the development of a new addition to their existing Hotel/Casino operation, which included an underhung monorail, that was envisioned to carry a parade of floats in the cavernous lower portion of the hotel, as part of a Las Veg as show. Planning, design, and engineering were completed by LG for all of the track alignment as a subconsultant to Creative Technology/Entertainment Engineering, including numerous switching structures, based upon initial rough plans from Harris Productions. LG defined X,Y,Z coordinates and attachment points to the complex overhead supporting hotel structure. Switch alignments were refined to enable higher travel speeds, and to have common components. LG also produced shop drawings for the switch structure on behalf of Intermountain Lift.

LG performed inspections for the guideway and power rail at the manufacturing facilities and supervised construction crews to install the power distribution system, power rail, transfer table and maintenance facility equipment.
Rehabilitation Design Project. The Lamoreaux Group, in association with Creative Technology, was retained by Dade County Florida to evaluate damage to the system and buildings caused by 173-mph hurricane winds and tornadoes from Hurricane Andrew, for the Dade County Metrozoo Monorail in Miami, Florida. This Universal Mobility, Inc. (UMI) monorail was originally installed to provide an overview of one of the world's largest modern open zoos. The maintenance facility and 1500' of track were heavily damaged, with the balance of the guideway and stations in need of major repairs. LG and Creative Technology along with Joint Venture Partner BRV formed a partnership to design and build the repairs, including replacement of the guideway, column replacement and column repairs, partial power rail replacement, guideway painting, station/building repairs, maintenance vehicle storage building repairs, and hurricane structural retrofits for the entire system to prevent future damage from similar hurricanes.
